Why can I thumbnail some of my CorelDRAW! files?
ThumbsPlus can only read the thumbnail preview directly from CDR, CMX and PAT files. If the files were not saved with a preview bitmap, then ThumbsPlus will report “error reading file.” Note that you can set up ThumbsPlus to use OLE with CorelDRAW! to thumbnail and view the files, but this is very much slower than reading the preview bitmap directly.
